I’m looking to update my laptop memory and purchasing the new DDR4 memory has too many options, ranging from pin count to speed and sizes. I am looking to get the fastest and biggest memory i can use for both DIMM slots. There’s a speed issue, can i use 3200mhz (or higher if available), and 2x32gb memory ( or 2x16gb?). Also i noticed that when i went on line searching for this, i found out that there are DIMM slots with varying PIN numbers, some being 250 while others being 260. I have an i7 processor in the motherboard. Any help in this matter would be of great help. Thank you
